Abstract

An improved extractable barrel-arbor for a watch movement is provided with first and second end cylindrical pivot bearing surfaces, and a central cylindrical surface containing a hook. The radius of the central surface is less than the radius of the first and second end cylindrical surfaces while the distance between the axis of the barrel-arbor and the outer hooking edge of the hook is equal to the radius of at least one of the first and second pivot bearing surfaces.
